There's still a solid loyal following for manual transmission in NA and BMW is aware of that - example is the 6MT being available on the new M5 for the NA market exclusively. And xDrive sells very well here, so I don't think we have to worry about either not making it here IMO.
If it's just a power boost and few suspension tweaks, I doubt it will be worth it. If however it gets the torque vectoring xdrive fm the X6 or a mechanical LSD with rear wheel drive, I think many ppl will be interested.
